Ok, this is my first thread so I hope I don't mess things up.

I have a 2008 supercrew 4x4. I REALLY wanted to get bilsteins to level mine out but I don't think I'll have the money so I'm thinking about the 2.5 autosprings kit. My question is should I go with a 3 inch block, 1.5 AAL, or a 1.5 lift shackle in the back? I have searched and searched but no clear results. I know the AAL is better for towing and can create a stiffer ride. The blocks I'd heard could crack? And I don't know much anything about the shackles... Any help would be great.

Thanks guys!

 

I would go with the 3" block. I got mine from Fat Bobs Garage. They call it a 1" block but it's actually a 3" with a 1" over stock after you remove the factory 2".

Never heard of blocks cracking. That's a new one on me.
